Nonaqueous electrolyte battery having large capacity and long cycle life

摘要

It is intended to provide a nonaqueous electrolyte battery that satisfies both of a large discharge capacity and a superior cycle life characteristic by developing a novel negative electrode material. A nonaqueous electrolyte battery uses a negative electrode active material that is a compound expressed by Formula (1):; ;where A is at least one element selected from the alkali metals, M is at least one element selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ru, Rh, Pd, Os, Ir, Pt, and Mg, X is at least one element selected from the group consisting of B, N, Al, Si, P, Ga, Ge, As, In, Sn, Sb, Pb, and Bi, 0z20, and 0.2y6.
